Now I am a contractor, not a painter. Correct me if I am wrong, but I have been told by many of my painters that if you finish spray the trim with any gloss it will affect how your flat goes on the wall, where it overlaps. Thanks
The gloss from the trim on the drywall can create at least two potential issues:
1) the flat paint won't adhere to the trim paint. The trim paint needs to be scuff sanded before the flat paint is applied.
2) many painters use cheap PVA primers on drywall. These do a horrible job of sealing the surface. The areas where trim paint is on the drywall will be sealed and this will cause a sheen difference.
